Abstract: A structure having an optical slit therein. The structure includes a substrate having an opening therethrough and a metal layer disposed on the substrate, such metal layer having a photolithographically formed slit therein, such slit being narrower than the opening and being disposed over the opening, portions of the metal layer disposed adjacent the slit being suspended over the opening and other portions of the metal layer being supported by the substrate.

Abstract: A passive reflective tracking media includes a plurality of multi-layer particles including at least one layer of a high refractive index material and at least one layer of a low refractive index material. The particles are configured to reflect ambient electromagnetic radiation at one or more signature wavelengths. Methods of applying the tracking media to a target object, detecting the tracking media, and fabrication the tracking media are also described.

Abstract: A microelectromechanical (MEM) device includes a substrate and a flexible cantilever beam. The substrate has positioned thereon a first interconnection line separated by a first gap and a second interconnection line separated by a second gap parallel to the first interconnection line. The substrate also has positioned thereon a first and second primary control electrode wherein one of the first and second primary control electrodes is positioned on one side of one of the first and second interconnection lines and the other one is positioned on the other side of the other first and second interconnection lines. The flexible cantilever beam has a top surface and a bottom surface and a beam width slightly larger than the gap widths at the gaps. A flexible anchor is secured to the bottom surface of the beam at a center of the beam and attached to a center of the substrate so as to position the beam orthogonally to the first and second interconnection lines.
